About this product

CONFORDAN 900

CONFORDAN 900 is a two-layer product: a high-density self-adhesive bitumen membrane and a chemically cross-linked polyethylene heat-sealed to it. It provides acoustic mass to the surface and removes resonant frequencies.

CONFORDAN 900 HS is a multilayer product: a high-density membrane, a chemically cross-linked polyethylene heat-sealed to it, finished with a heat-sealed geotextile. Thanks to its low height it allows the acoustic rehabilitation of old floor slabs without the need to remove the floor.

Uses: high-acoustic-performance flooring systems (hotels, residential homes, etc.), acoustic rehabilitation of floor slabs, complement to the IMPACTODAN® system, and a moisture and separating barrier for floating wood floor finishes. The 900 HS is designed for the direct bonding of ceramic floor tiles in renovation.
